Guangyou 2643, a new hybrid rice combination, was developed by Fujian Sanming Institute of Agricultural Sciences, which was crossed with the own breeding parents -- a CMS line Guangkang 13 A and a restorer line Minghui 2643. It was characterized by high yield and resistant blast. It was released by state and Fujian Longyan in 2009. We introduced its breeding process, main characteristics, key cultivation and hybrid seed production techniques.
